Pennsylvania has awarded the Redevelopment Authority of Montgomery County a $1 million grant toward the clean-up of a 4.6-acre asbestos-contaminated site in Ambler, at the former Keasbey & Mattison property, Gov. Wolf's office announced Tuesday.

The money from Pennsylvania's Industrial Sites Reuse Program will be used for excavation and disposal of contaminated soil and asbestos-containing material, the installation of an environmental cap, and other measures.

A 134,205-square-foot, 115-unit apartment building is in the works for the site, which became part of the U.S. Environmental Protection Agency's Superfund program in the 1980s. Keasbey & Mattison, which manufactured automotive-construction products, ultimately became part of Armstrong World Industries.
